LUBRICATOR.

SPECIFICATION forming part of Letters Patent N o. 588,566, dated August24, 1897.

Application filed March 16, 1897. Serial No. 627,820. (No model.)

To all whom it 11m/,y concern:

Be it known that I, HENRY GLANZ, a citizen of the' United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented a new and useful Lubricator, of which thefollowingis a speciiieation.

My invention relates to lubricators adapted for use in connection withsteam-engine and pump cylinders and similar devices, and has for itsobjects to provide a simple and eflicient construction and arrangementof parts whereby the application of the lubricator to the cylinder isfacilitated, to provide simple and efficient means whereby broken orinjured parts may be replaced, and, furthermore, to provide meanswhereby the oil in the oil chamber or reservoir may be wholly dischargedbeforewater of condensation is allowed to enter the outlet-passage ofthe apparatus.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a vertical sectional view of a lubricatingdevice constructed in accordance with my invention. Fig. 2 is a detailvertical section of the Water-passage on the plane indicated by theline2 2 of Fig 1. Fig. 3 is a detailtransverse section of the main pipecontaining the steam and oil passages on the plane indicated by the line3 3 of Fig. 1. y

Similar numerals of reference indicate corresponding parts in allthefigures of the drawings.

1 designates a main tube or pipe constituting the stem of the apparatus,and this pipe is divided interiorly by a longitudinal diametricalpartition 2 to form parallel steam and oil passages 3 and 4, both ofWhich are formed within the contour of the cross-sectionally round pipe.that this construction of the main stem or pipe enables the entirecapacity of the pipe to be utilized With the exception of that which isoccupied by the thin partition 2. The steam and oil passages areprovided, respectively, With an inlet 5 and an outlet 6, formed indiametrically opposite Walls thereof.

`pipe 9.

It will be understood- Communicating with the steam-passage 3 1s avertical branch 7, which in turn communicates With acondensation-chamber 8, said branch pipe 9 and is fitted With a secondcutoff 13, and the water-passage 11 is spread or carried around theoil-passage, as shown at 11a, and communicates With" a sleeve 14,

`formed in the under side of the main pipe or stem, preferably inalinement with the branch the condensation-chamber, ata point near thebottom of the oil-chamber; -This oilchamber is fitted Wit-h ailling-pluglS and hopper 19, and also in its bottom Witlian outlet orrelief valve 20, of which the'upvva'rdlytapered seat 21 is adapted toclose a plurality of branches 22, with which the axial bore 23 of saidvalve is provided. The object of this outlet or .relief valve is toWithdraw Water of condensation from the oil-chamber when it is desiredto introduce a fresh vsupply of oil. Also, communicating with theinterior of the oil-chamber and preferably arranged within the contourthereof, with its extremity contiguous to the plane of the upper Wall ofthe chamber, is a discharge-tube 24, and the top of the oil-chamber ispreferably provided, in alinement with said tube or passage, with aremovable plug 25 to facilitate the cleaning of the tube or passage. Theoutlet-tube coinmunicates by means of a branch 26 with the casing of aregulating-valve 27 and oil enter-` ing said casing and passing thevalve-seat28 is conducted by a reducing-nozzle 29 into a sight-tube 30,preferably mad-e of glass or its equivalent. The lower extremity of thissight-tube is seated around the nozzle 29 and is secured in place bymeans of the cap 3l of IOO a packing-box, while the upper end of thesight-tube is seated in a sleeve 32, formed in the. extremityof theextension 4 ot' the abovedescribed oil-passage 4, and is held in placeby means of a cap 33, forming a packing-box. In the diametricallyopposite side of the extension 4, in alinement with the sight-tube, is aplug 34, of larger diameter than the seat provided for the sight-tube,whereby a new sight-tube may be introduced therethrough, orthesight-tube may be removed i'or the purpose of cleaning.

I have found in practice that as the lubricant is raised in the oilchamber or reservoir by the influx of water of condensation there is aliability of the accumulation of a portion of the lubricant upon the topof the reservoir, or the water begins to escape through the tube 24 orits equivalent before all of the oil has been discharged. As a resultthe operation of the lubricator must be stopped and the water withdrawnto give place for a fresh supply of oil, and any oil on the top of thewater which has not been discharged is thereby wasted. To avoid this, Ihave adopted an inclined top or root' in connection with the oilchamber,which inclines upwardly toward the inlet end of the outlet-tube 24. Thisarranges said inlet end of the tube at the uppermost point ot' the oilchamber or reservoir, and at the same time the inclined roof, of whichthe depressed or lowermost portion is arranged in a lower plane than theextremity of the tube, causes the oil, which of' course floats upon thesurface of the water, to be concentrated at a point graduallyapproaching the extremity of the outlet-tu be as the surface of thewater rises, until, as the surface of the water approaches the plane ofthe extremity of the tube 24, the only remaining oil in the reservoir isconcentrated in a small area in close proximity to the tube, andtherefore must escape before the water of condensation can reach thelevel of the mouth of `the tube.

Then it is desired to refill the oil chamber or reservoir, the cut-ott'valve 12 and the regulating-valve 27 must be closed, and when it isdesired to clean or introd ucc a new sight-tube the cut-off valve 13 andthe regulating-valve must be closed.

It will be understood that while the abovedescribed construction of theconnection between the pipe containing the inlet and outlet said pipemay be cast integral with the oilreservoir and bored out to form thechannels.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having described my invention, what I claim is 1. In a lubricator, thecombination of a main supporting pipe or stem, having separate steam andol passages and independent contiguous inlet and outlet openings, abranch steam-passage, in communication with a condensation-chamber, anoil-chamberhavingits top inclined upwardly, in a common plane, to apoint near one side ofthe chamber and having an inlet-tube incommunication with the condensation-chamber,adischarge-tubecommunicating at one end with the oil-chamber contiguous to saiduppermost point of its t'op, and in alinement with a removably-pluggedopening in the top of the chamber, a passage, including a sight-tube,connecting the other end of the discharge-tube with the said oilpassage,and a regulating -valve arranged in said connecting-passage,substantially as specified.

2. A lubricator having a main supporting pipe or stem l having separatesteam and oil passages 3 and 4, a condensation-chamber, a branch pipehaving separate steam and water passages 7 and l1, of which the formerisin communication with the steam-passage of the main pipe or stem, theoil-passage ot' the main pipe or stem being extended, as at 4, beyondthe point of intersection of said branch pipe, and the water-passagebeing divided and carried around the extension of the oil-passage tocommunicate with a sleeve 14, an oil-chamber having a thimble 15 fittedin said sleeve and being provided with inlet and outlet tubes 17 and 24,filling and cleaning plugs 18 and 25, and a top which is inclinedupwardly from the filling-plug to the cleaning-plug, the latter being inalinement with the outlet-tube, and a valved connection between theoutlettube and said oil-passage, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses HENRY GLANZ.
